Relaxin action in the heart, kidney, lung and uterus: understanding fibrosis. Relaxin is a peptide hormone associated with pregnancy. We have recently generated a relaxin gene knockout mouse and exciting preliminary data show that without relaxin, non-pregnant mice develop signs of fibrosis in the heart, lung and uterus. Combining our expertise in molecular biology, pharmacology and physiology, the overall objective of this project is to investigate the functions and mechanisms of relaxin action ....Relaxin action in the heart, kidney, lung and uterus: understanding fibrosis. Relaxin is a peptide hormone associated with pregnancy. We have recently generated a relaxin gene knockout mouse and exciting preliminary data show that without relaxin, non-pregnant mice develop signs of fibrosis in the heart, lung and uterus. Combining our expertise in molecular biology, pharmacology and physiology, the overall objective of this project is to investigate the functions and mechanisms of relaxin action in these organs. Our findings will provide important basic information on relaxin physiology and enable us to implement a long-term partnership with Connetics to understand how relaxin regulates collagen production and/or the development of fibrosis.Read moreRead less
Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' t ....Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' to birds since they see colours differently from humans. We will determine bird spectral sensitivities and compare them to the spectral reflectance of wind-farms. We will then develop modifications improving the visibility of wind-farms to birds, thereby reducing fatalities.Read moreRead less
Relaxin: molecular mechanisms of action in the reversal of fibrosis. Defects in relaxin and relaxin receptors are increasingly implicated as a cause of fibrosis which is associated with many disease processes. This study will examine the molecular mechanisms linking relaxin and fibrosis and will determine whether relaxin can be used to reverse the condition.
What is the spatial and environmental distribution of phylogenetic diversity in the Australian biota? Almost nothing is known about the geographic distribution of phylogenetic relationships across Australia at fine resolutions of the order of tens of kilometres. The aim of this research is to map the spatial patterns of phylogenetic diversity in the Australian biota and identify possible environmental controls over them. We will analyse five disparate groups at a spatial resolution that is ord ....What is the spatial and environmental distribution of phylogenetic diversity in the Australian biota? Almost nothing is known about the geographic distribution of phylogenetic relationships across Australia at fine resolutions of the order of tens of kilometres. The aim of this research is to map the spatial patterns of phylogenetic diversity in the Australian biota and identify possible environmental controls over them. We will analyse five disparate groups at a spatial resolution that is orders of magnitude finer than previous research, analysing their relationship with possible environmental controls using advanced spatial analysis methods. The knowledge we will generate about the spatial distribution of these relationships is essential to understand and conserve Australia's unique biodiversity.Read moreRead less
Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on ....Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on Australia's ocean biology, fisheries and biotechnology never before approachable. To be effective guardians of Australian waters we must learn what lies in the depths we can't see from a boat.Read moreRead less
Environmental Toxicology of Marine Turtles in the South Pacific Region. We propose to study pollutants such as pesticides, polychlorinated biphenyls (PCBs), and metals in sea turtles. Drs Whittier (UQ) and Henry Olszowy (Queensland Health Scientific Services) will supervise a Ph.D. student in the research. We will identify significant pollutants in Queensland, the Solomon Islands and Malaysia at sea turtle nesting and feeding grounds. We will follow the fate of chemicals in female turtles and t ....Environmental Toxicology of Marine Turtles in the South Pacific Region. We propose to study pollutants such as pesticides, polychlorinated biphenyls (PCBs), and metals in sea turtles. Drs Whittier (UQ) and Henry Olszowy (Queensland Health Scientific Services) will supervise a Ph.D. student in the research. We will identify significant pollutants in Queensland, the Solomon Islands and Malaysia at sea turtle nesting and feeding grounds. We will follow the fate of chemicals in female turtles and the effects of contamination on the development of eggs and hatchlings. This information will be used to help manage sea turtle populations and to contribute to sustainable use of the animals for a growing ecotourism industry.Read moreRead less
Vision and remote sensing: using nature's technology to examine the health of The Great Barrier Reef and Moreton Bay. We aim to use what is known and what we will discover about animals visual systems to examine environmental health on The Great Barrier Reef and Moreton Bay. Technology and knowledge from 8 university departments, 4 industry partners, and 7 international collaborators will be combined to both learn and provide information. The innovative aspect of our approach is to examine the w ....Vision and remote sensing: using nature's technology to examine the health of The Great Barrier Reef and Moreton Bay. We aim to use what is known and what we will discover about animals visual systems to examine environmental health on The Great Barrier Reef and Moreton Bay. Technology and knowledge from 8 university departments, 4 industry partners, and 7 international collaborators will be combined to both learn and provide information. The innovative aspect of our approach is to examine the world with the eyes of birds, fish and invertebrates. Tricks animals employ to solve visual tasks will be implemented at scales of instrumentation from hand-held to remote sensing and used to address problems such as coral reef bleaching.Read moreRead less
